OxTalks is Changing
OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, please contact halo@digital.ox.ac.uk
'How DUBs decode ubiquitin signals and how they are inhibited - Insights into USP30 and beyond'
Post-translational modifications composed of ubiquitin regulate a wide range of cellular functions and are tightly controlled by deubiquitinating enzymes (DUBs). The recent start of clinical trials with inhibitors of two DUBs highlights the therapeutic potential of their modulation in cancer and neurodegenerative diseases. However, how DUBs decode ubiquitin signals and how they are engaged by small molecule ligands remain poorly understood at the molecular level. My group uses an integrated chemical and structural biology approach to shed light on how DUBs function and how they can be specifically inhibited. In my talk, I will discuss recently published and unpublished projects: I will focus on how protein-based probes have enabled the discovery of novel activities in DUBs. Moreover, I will cover how a chimeric protein engineering approached revealed how the mitophagy-regulating DUB USP30 can be specifically inhibited and how this provided a framework for specific DUB inhibition.
